in the instrument cluster graphic) to the vehicle’s recom-
mended cold placard pressure value as shown in the
⬙Inflate to XX⬙ message. Once the system receives the
updated tire pressures, the system will automatically up-
date, the pressure values in the graphic display in the
instrument cluster will return to their original color, and
the “Tire Pressure Monitoring Telltale Light” will turn off.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to receive
this information.
Service TPMS Warning
When a system fault is detected, the “Tire Pressure Moni-
toring Telltale Light” will flash on and off for 75 seconds
and then remain on solid. The system fault will also sound
a chime. In addition, the instrument cluster will display a
⬙SERVICE TPM SYSTEM⬙ message for a minimum of five
seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.
If the ignition is cycled, this sequence will repeat, provid-
ing the system fault still exists. If the system fault no longer
exists, the “Tire Pressure Monitoring Telltale Light” will no
longer flash, and the “SERVICE TPM SYSTEM” message
will no longer display, and a pressure value will display in
place of the dashes. A system fault can occur due to any of
the following:
• Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Lots of snow or ice around the wheels or wheel hous-
ings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare — If Equipped
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not moni-
tor the pressure in the compact spare tire.
2.
If you install the compact spare tire in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition cycle, the “TPM Telltale Light” will
remain on and a chime will sound. In addition, the graphic
in the instrument cluster will still display a different color
pressure value and an ⬙Inflate to XX⬙ message.
